SN74F86D

Overview

The SN74F86D is a quadruple 2-input exclusive-OR gate in the 74F logic family, housed in a 14-pin Small Outline (D) package. It operates on a supply voltage of 4.5V to 5.5V with an operating temperature range of 0°C to 70°C. Electrical characteristics include a high-level output current of -1mA and a low-level output current of 20mA. Propagation delay ranges from 3ns to 8ns depending on input conditions.

Feature Summary

• Contains four independent 2-input exclusive-OR gates for Boolean logic operations
• Functions as a true/complement element by reproducing or inverting signals based on input states
• Supports applications such as parity generation and signal inversion

Applications

• True/complement element implementation
• Even-parity generation
• Odd-parity generation

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package markings match the 'F86' identifier. Ensure compatibility with existing PCB layouts designed for the SOIC-14 footprint. Validate that the 0°C to 70°C temperature range meets system requirements.

Selection Notes

Select this component for standard TTL-compatible logic designs requiring exclusive-OR functionality. The 74F series offers faster switching speeds compared to LS variants. Verify that the 14-pin SOIC package fits the available board space. Consider the -1mA high-level output drive capability when designing load circuits.

Part Context

This device belongs to the Texas Instruments 74F logic family, known for high-speed performance. It is part of the broader SN74F86 series, which includes various packaging options like DIP and tape-and-reel formats. The D suffix specifically denotes the plastic small-outline package configuration.

Replacement Considerations

SN74F86DR: Active production version in tape-and-reel format. SN74F86NSR: Active SOP variant with different pin pitch. SN74F86N: Active PDIP through-hole alternative.
